-/* **************************************************************************
- *
- * Set of malloc/realloc/calloc/strdup/free replacement macros that
- * insert some extra words around each allocation for debugging purposes
- * and also attempt to detect invalid uses of the malloc heap through
- * various tricks like inserting clobber words at the head and tail of
- * the user's area, delayed free() calls, and setting the memory to
- * a fixed pattern on allocation and when freed. The allocations also
- * can include warrants so that when an area is clobbered, this
- * package can report where the allocation took place.
- * The macros included are:
- * malloc(size)
- * realloc(ptr,size)
- * calloc(nelem,elsize)
- * strdup(s1)
- * free(ptr)
- * malloc_police() <--- Not a system function
- * The above macros match the standard behavior of the system functions.
- *
- * They should be used through the include file "debug_malloc.h".
- *
- * IMPORTANT: All source files that call any of these macros
- * should include debug_malloc.h. This package will
- * not work if the memory isn't allocated and freed
- * by the macros in debug_malloc.h. The important issue
- * is that any malloc() from debug_malloc.h must be
- * freed by the free() in debug_malloc.h.
- *
- * The macros in debug_malloc.h will override the normal use of
- * malloc, realloc, calloc, strdup, and free with the functions below.
- *
- * These functions include:
- * void *debug_malloc(size_t, void*, int);
- * void *debug_realloc(void*, size_t, void*, int);
- * void *debug_calloc(size_t, size_t, void*, int);
- * void debug_free(void *, void*, int);
- *
- * In addition the function debug_malloc_police() can be called to
- * tell you what memory has not been freed.
- * void debug_malloc_police(void*, int);
- * The function debug_malloc_police() is available through the macro
- * malloc_police(). Normally you would want to call this at exit()
- * time to find out what memory is still allocated.
- *
- * The variable malloc_watch determines if the warrants are generated.
- * warrants are structures that include the filename and line number
- * of the caller who allocated the memory. This structure is stored
- * at the tail of the malloc space, which is allocated large enough
- * to hold some clobber words at the head and tail, the user's request
- * and the warrant record (if malloc_watch is non-zero).
- *
- * The macro LEFT_OVER_CHAR is what the trailing bytes of an allocation
- * are set to (when the allocation is not a multiple of 8) on allocation.
- * At free(0 time, these bytes are double checked to make sure they were
- * not clobbered. To remove this feature #undef LEFT_OVER_CHAR.
- *
- * The memory freed will have the FREED_CHAR put into it. To remove this
- * feature #undef FREED_CHAR.
- *
- * The memory allocated (not calloc'd) will have the ALLOC_CHAR put into it
- * at the time of allocation. To remove this feature #undef ALLOC_CHAR.
- *
- * The macro MAX_FREE_DELAY_COUNT controls how many free blocks will
- * be kept around before being freed. This creates a delayed affect
- * so that free space that gets clobbered just might get detected.
- * The free() call will immediately set the user space to the FREED_CHAR,
- * leaving the clobber words and warrant in place (making sure they
- * haven't been clobbered). Then the free() pointer is added to a
- * queue of MAX_FREE_DELAY_COUNT long, and if the queue was full, the
- * oldest free()'d memory is actually freed, getting it's entire
- * memory length set to the FREED_CHAR.
- *
- * WARNING: This can significantly slow down an application, depending
- * on how many allocations are made. Also the additional memory
- * needed for the clobber words and the warrants can be significant
- * again, depending on how many allocations are made.
- * In addition, the delayed free calls can create situations
- * where you might run out of memory prematurely.
